I wouldn't worry that the FSSP is too "new". It is actually 25 years old, so its been around a while and is still going strong. The communities it serves tend to be fairly stable and produce good numbers of vocations, so I think its future is secure. Besides, nothing in this world is forever. If you are attached to the EF, I think you should definitely consider the FSSP.
The FSSP is also an institute of pontifical right - the highest approval and, you might say, has the highest protection and stability that is offered - the pope. At the lower levels of approval, e.g., of "diocesan right", the bishop can at any time, remove them from his diocese or dismantle them altogether - caput. With pontifical status, the bishop does not have the authority to do this anymore, only the Holy See can dismantle the institute or remove them.
At this time I wouldn't worry about the stability of the FSSP or the EF at all. If anything, both are growing rapidly. I don't think it's the form of the Mass that should cause worry, but those who take traditionalism to the point of going against the Pope and the Magisterium. Remember the FSSP was set up by the pope to counter the separation of the SSPX.
Keep praying, go to daily Mass, read the lives of the saints, and consecrate yourself to Our Lady, placing your vocation in Her loving hands, She who formed our great High Priest, is the Queen of heaven, and can obtain any and all graces for you.
Happy feast of Our Lady, Mediatrix of All Graces. Ave Maria!
In the Sacred Hearts of Jesus and Mary,
Friar John Paul
